PS3 Kmeaw 3.55 CFW on PSN

i'm on 3.41, but i want PSN acess to play netflix, multiplayer games. 2 questions, i have a slim ps3 can i downgrade later to 3.41 if i go with cfw 3.55, also which cfw is working right now with PSn for multiplayer and netflix thats well recomended??

i haven't messed with my jb in a long time and since then all of advancements have been made, that's why it sounds real noobie...

I'm really interested in netflix and as far as Psn or multiplayer, i'm sure it's being worked on, in just wondering how i can use netflix on 3.41 since no psn on 3.55 cfw because when i go into netflix app it says i have to login to psn so i tried just to see what happens it says i need a system update ??

I think there might be workarounds for that netflix... I'll search and see what I can find, but other than that a Wii would be the next best thing i guess since it connects to netflix fine modded or not
